Abstract
A method and system for controlling the spatial distribution of radiation produced by a radiation device having a multi-leaf collimator can generate arbitrary intensity-modulated radiation fields. The methods control both angles and leaf configuration of the multi-leaf collimator for each of multiple sub-fields. The leaf positions, collimator angles, and individual sub-field contributions may be derived by optimization techniques.
